MIL-STD-810F

In order for a piece of electronics to be approved for use for Department of Defense (DoD) and other government agencies, these electronics must pass through standardized testing. The test method that makes electronics approved for use by all Department and Agencies of the Department of Defense is commonly referred to as "military standards" or "MIL Specs." These rugged specifications, were created specifically for DoD applications, the MIL Specs are commonly tailored for commercial applications. Military standards began with MIL-STD-810E and were then revised to produce more rugged electronics with the MIL-STD-810F. The newest revisions helped to provide clear directions in regards to ruggedized testing for military grade laptop and tablets.

The 810E and 810F were created for the same outcome; to provide testing procedures to help create military grade laptops and other electronic devices. These specifications help tailor a material and a design to suit different environmental conditions that may be experienced in the line of duty. The "F" revision however, expands the up front understanding on how to implement the environmental tailoring process throughout the materiel acquisition cycle.

This revision recognizes that the environmental design and test tailoring process has expanded to involve a wide range of managerial and technical interests. Accordingly, this revision orients environmental design and test direction toward three basic types of users who have distinctly different, although closely associated, interests: program managers who, among other responsibilities, ensure proposed concepts and systems are valid and functional in intended operational environments; environmental engineering specialists (EES), who enter the acquisition process early to assist combat and materiel developer tailoring efforts by preparing life cycle environmental profiles and drafting tailored design criteria and test programs, and the design, test, and evaluation community, whose analysts, engineers, and facility operators use tailored designs and tests to meet user needs.

Military standards must be followed to assure proper design, manufacturing standards, durability, and uniform electronic requirements. All of these requirements encompass processors, battery, memory, power devices, essential and nonessential operating devices. When a device does not meet certain military specifications it cannot be of use to any Department or Agencies that are affiliated with the Department of Defense.

TERMINOLOGY DEFINITION:

a. Accelerated test. A test designed to shorten the controlled environmental test time with respect to the service use time by increasing the frequency of occurrence, amplitude, duration, or any combination of these of environmental stresses that would be expected to occur during service use.

b. Aggravated test. A test in which one or more conditions are set at a more stressful level than the materiel will encounter during service use.

c. Ambient environment. The conditions, either outdoor or confined (e.g., temperature and humidity), that characterize the air or other medium that surrounds materiel.

d. Climatic categories. Specific types of world climates which materiel is designed to withstand during operation, storage, and transit.

f. Critical threshold value. The level of an environment forcing function that degrades the capability of materiel significantly or requires degradation prevention measures be taken.

g. Cumulative effects. The collective consequences of environmental stresses during the life cycle of materiel.

h. Engineering judgment. Expert opinion based on engineering education and experience, especially in the area in which the judgment is made.

i. Environmental analysis. Technical activity covering an analytical description of the effects that various environments have on materiel, subsystems, and component effectiveness.

j. Environmental conditions. (See Forcing function (environment).)

k. Environmental engineering. The discipline of applying engineering practices to the effects that various environments have on materiel effectiveness.

l. Environmental engineering specialist (EES). A person or group of people skilled in one or more environmental engineering areas. Areas include, but are not necessarily limited to: natural and induced environments and their effects on materiel; expertise in measuring and analyzing in-service environmental conditions; formulating environmental test criteria; determining when environmental laboratory tests are appropriate/valid substitutes for natural in-service environmental tests; and evaluating the effects of specific environments on materiel.

m. Environmental test. A structured procedure to help determine the effects of natural or induced environments on materiel.

n. Environmental Worthiness. The capability of materiel, subsystem, or component to perform its full array of intended functions in intended environments.

o. Equipment. For purposes of this standard, equipment includes the instrumentation, facilities, and support apparatus used to conduct or monitor tests. This does not include the test item itself or the materiel of which the test item is a sample or a part.

p. Forcing function (environment). A natural or induced physical environmental stress condition on materiel that may affect its ability to function as intended or to withstand transit or storage during its service life. (Also referred to as an environmental condition or an environmental stress.)

q. Hermetic seal. A permanent, air-tight seal.

r. Induced environment. An environmental condition that is predominantly man-made or generated by the materiel platform. Also, refers to any condition internal to materiel that results from the combination of natural environmental forcing functions and the physical/chemical characteristics of the materiel itself.

s. In-service use. The anticipated use of materiel during its intended service use life.

t. Integrated Product Team (IPT). A group of individuals from different professional disciplines and organizations (government and industry) who work together on a product from concept through production stages. Individuals who cover a discipline may change from stage to stage, but the discipline is covered, and the information pertinent to that discipline is passed to the succeeding team member(s) in that discipline.

u. Life Cycle Environmental Profile (LCEP). Design and test decision baseline document outlining real-world, platform-specific, environmental conditions that a specific materiel system or component will experience during service-related events (e.g., transportation, storage, operational deployment/use) from its release from manufacturing to the end of its useful life.

v. Life cycle profile. A time history of events and conditions associated with materiel from its release from manufacturing to its removal from service, including demilitarization. The life cycle should include the various phases materiel will encounter in its life, such as: packaging, handling, shipping, and storage prior to use; mission profiles while in use; phases between missions such as stand-by or storage, transfer to and from repair sites and alternate locations; and geographical locations of expected deployment.

ff. Service life. Period of time from the release of materiel from the manufacturer through retirement and final disposition.

gg. Tailoring. The process of choosing design characteristics/tolerances and test environments, methods, procedures, sequences and conditions, and altering critical design and test values, conditions of failure, etc., to take into account the effects of the particular environmental forcing functions to which materiel normally would be subjected during its life cycle. The tailoring process also includes preparing or reviewing engineering task, planning, test, and evaluation documents to help ensure realistic weather, climate, and other physical environmental conditions are given proper consideration throughout the acquisition cycle.

hh. Test item. Specific materiel, a subsystem, or component being tested, including its container and packaging materials, that is representative of the materiel being developed. A representative sample of materiel that is used for test purposes.
